Sleep in JavaScript

Many programming languages have a built-in sleep function that pauses a program’s execution for a given number of seconds, often making it easier to add delays. However, JavaScript, being an asynchronous and non-blocking language, doesn’t come with such a built-in feature.

This is simple code snippet that demonstrates how to create a sleep function in JavaScript that pauses the execution.

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

console.log("Task 1 started");
await sleep(2000);  // Wait for 2 seconds (2000 milliseconds)
console.log("Task 1 finished after 2 seconds");

console.log("Task 2 started");
await sleep(1000);  // Wait for 1 second (1000 milliseconds)
console.log("Task 2 finished after 1 second");
